Introduction
Overview
The CE250AKVM Extender allows access to a computer system from a remote
console (keyboard, monitor, and mouse). It is perfect for factory and
construction sites, or any type of installation where the console needs to be in
a conveniently accessible location, but you want the system equipment to
reside in a safe place – away from dust, dirt, and harsh environmental
influences.
The CE250Ais also useful for control and security purposes, since you can
store the system unit in a secure area at the same time that you put the console
in a location that offers convenient access.
The CE250AKVM Extender provides the ideal means to access the remote
system box, since it improves on previous designs by using compact,
inexpensive Cat 5 cable – the kind commonly used in Ethernet networks –
instead of bulkier, more expensive, standard cables. Cat 5 makes for a much
neater, more convenient, more reliable data transfer connection.
A key feature of the CE250Ais built-in 8KV ESD protection and 2KV surge
protection. It also features a custom ASIC that ensures the utmost in reliability
and compatibility. It senses the distance to the system and automatically
adjusts the gain to compensate.
Setup is as easy as can be – simply connect the computer system box and local
console to the Local CE250Amodule, run the Cat 5 cable to the Remote
CE250Amodule (up to 150 meters away); and plug the remote console into the
Remote Module.
Note: You can control numerous remote systems from a single console by
combining the CE250Awith a KVM switch.
